| Parameter description : |
| ----------------------- |
| Touches can be accelerated by not locking a source before updating |
| its time stamp. |
| The risk is that in rare cases outdated time stamps can be written |
| to a source and/or its load. As a consequence, a load in the PXA |
| buffer will appear newer than the source, which isn't the case. |
| The load will appear to be valid and generated from the source. |
